' (o1. 2o e2) V 7 Claims.

v .1 V This invention relates to a jalo-usie, more'particularly, to an improved form of crank-operated jalcusie.

It is an object of the present invention to provide a jalousie of the crank-operated type wherein several of the mechanical elements employed to operate the slats of the jalousie are concealed from view. I

It is a further object of the invention to provide an improved form of jalousie which provides enective weather stripping without unsightliness.

It is a still further object of the invention to provide a jalousie wherein the'slats form a tight closure without a marked tendency to bind, or to develop cracks on shrinking.

These and other objects of the invention will be apparent from the ensuing description and the appended claims. v

One form which the invention may assume is exemplified in the following description and illustrated by way of example-in the accompanying drawings, in which:

Fig. 1 is a longitudinal mid-section through the jalousie of the invention.

Fig. 2 is a section takenalong the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary, perspective view of the slats of the jalousie as seen from their exterior. Fig. 4 is a section taken along the line 4-4 of Fig. 1, partly broken away and with the slats removed, showing the means, of mounting and concealing the mechanical elements employed to operate the slats and also showing details of the weather stripping. Figs. 5 and 6 are sections taken along the lines 5-5 and 6-6, respectively, of Fig. 4, showing details of the mechanical elements employed to operate the slats.

Referring now to the drawings, a window frame I is provided comprising the usual sin 2, head rail 3 and jambs 4 which, however, are modified as described hereinafter. A plurality of slats I are provided, including a stationary slat I I at the top and any desired number of pivotal slats I2 therebelow. The stationary slat I I is secured to the rail 3 by any suitable means, as by a mortise and tenon joint at I3 and nails I4, and a sealing member or staff mold I is also provided to provide a seal between the rail and the wall I6.

The pivotal slats I2 are supported by means of levers I! (a pair of which are secured to opposite sides of each slat I2), pivot bars I8 (one such bar being secured to each jamb) and pivot pins I9 extending through each lever I1 and its adjacent pivot bar I8. Each lever I1 is generally of right angular cross section, and it is provided with an upwardly and inwardly extending arm 25 and, outwardly of the slats I 2, with a flange 26 of curvilinear transverse cross section havin an enlargement or boss 21 at its lower end. The levers I! are secured to the slats I2 by means of screws 28, and the pivot bars I8 are secured to the jambs by means of screws 29. It will also be noted that the pivot bars I8 extend outwardly of the slats I 2 and jambs 4, and that the position of the levers I? and the curvature of the flanges 26 are such that the latter abut the pivot bars when the slats are in closed position, thus providing a seal or weather stripping. Also, each boss 21 overlaps the next lower flange 21, thus providing a continuous seal the length of the window.

Each of the slats II, I2 is recessed orrabbeted at its lower end to provide a tongue 30 and a recess SI, and at its upper end each pivotal slat I2 is somewhat similarly rabbeted, except that the recess 3Ia is sloped upwardly, as shown, and extends inwardly of the tongue 30a to-provide a groove 32. The sill 2 is similarly rabbeted to provide a groove'33 and tongue 34.

It will thus be seen that each of the pivotal slats I2 can be pivoted outwardly to open position and inwardly to closed position, and that in the latter position the flanges 26 provide a weather stripping which is eifective and of'pleasing appearance. It is also apparent that, when the slats are in closed position, the rabbeted joints provide an effective closure and combine therewith a pleasing appearance. Also, the rabbeted joints are such as not to bind and as always to provide a tight closure even when the wood shrinks. Y i v e To operate the slats I2, there is p'rovided'a mechanism which will now be described; The usual travel bars 40 are provided, one at each side of the window, and the arms 25 of the levers I1 are pivotally connected to the travel bars 40 as at 4!. The lower end of each. travel bar 40 is pivotally connected at 42 to a link 43, the other end of which is pivotally secured at 44Qto a crank arm "45. Each crank arm 45 is secured to an operating shaft 46. At one end the operating shaft is received within a recess 41 formed in the jamb 4 and is journalled' in a bearin plate 48 secured to the adjacent jamb by means of screws 49. The other end of the operating shaft is journalled in a bearing plate 50 secured" to the jamb by means of screws and is received within a relatively large recess 56 formed in the jamb,

' for which the bearing plate 50 serves as a closure.

A worm wheel section 51 is secured to the operating shaft 46 within the recess 56, and an operating crank 58 journalled in the bearing plate 50 and in a bearing block 59 secured to the plate 50 is provided with a worm 60 integral therewith and in mesh with the worm wheel sector 57. A stop pin BI is also provided to limit angular movement of the worm wheel sector 5! and, hence, of the pivotal slats l2.

Crank means, including meshing gears, is thus provided for opening and closing the pivotal slats l2, which means is compactly arranged within one of the jambs of the window frame and is thus concealed from view.

It will thus be seen that a jalousie or Venetian blind structure is provided which affords several advantageous features. Thus, an effective, continuous weather strippin is provided, which is of pleasing appearance. between slats is provided, which does not or is less likely to bind or develop cracks on swelling or shrinking. Manually operable crank means of simple and rugged construction are provided but are concealed from view.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined by the appended claims Having thus; described my invention, what I claim and desire to secure by LettersPatent is:
